Ependymal cells are epithelial cells.

• A. True
• B. False
• C. Neurons
• D. Glial cells

Answer: (A)

Ependymal cells form the lining of the brain’s ventricles and the spinal cord’s central canal. They arise from neuroepithelium and create a continuous, polarized layer with features typical of epithelial tissue—apical cilia and microvilli to help move and exchange CSF, and intercellular junctions that contribute to a barrier. This lining role gives them epithelial characteristics, even though they are part of the CNS glial cell family. They are not neurons, but their primary function is to line and protect the CNS surfaces and support CSF dynamics, which is why describing them as epithelial cells is correct.
